You can click on the globe to move it around to the area you desire, scroll to zoom in, and clicking on the "Earth" button will give you other data to plot (cool!) For the wind map, the brighter the color, the faster the wind speeds.

It's easy to pick out the swirling storm systems and also gives you an idea of the trade winds near the equator -- the winds typically blow "backwards" down there, moving from east to west!

If you like this map, also be sure to check out hint.fm/wind, which shows a similar map for the United States and you can zoom closer here.
